IMPROVEMENT IN GATES FOR TURBINE WATER-WHEELS.

Specification forming part of Letters Patent To all whom it mayconcern.-

Be it known that we, ADAM MOESSINGER and WILLIAM HEATHOOTE, of GlenRock, in the county of York and State of Pennsylvania, have invented anew and useful Improvement in Gates for Turbine Water-Wheels, of whichthe following is a specification.

The object of our invention is to provide close and tight fitting gatesthat can be easily and exactly regulated for turbine waterwheels.

The invention consists in the arrangement of a circular or conical capwith slotted flanges operated by a rack and pinion, the flange coveringthe upper openings of the water-course, and of a slotted cylindricalring operated by an eccentric, which covers the lower openings of thewater-course.

In the drawings, Figure 1 shows a vertical cross-section; Fig. 2, aground plan, and Fig. 3 a detail view of the eccentric.

Similar letters of reference indicate corresponding parts.

Ais the frame of the turbine, and B B B are the water-courses. O is aconical or circular cap, provided with a flange, D, having slots E E,corresponding with the water-courses B B. This cap can be partiallyrotated by means of the rack F and pinion G on the shaft H, having ahand-wheel, I, and a bearing on the block J, which is attached to themain frame A of the turbine. K is the shaft of the turbine, and issecured to the plate L, which again is fastened to the frame of theturbine, as shown in Fig. 1. M is a spring wound around the shaft Kbetween the two bearing- On the upper bearing, N, is an adjusting-ring,O, by means of which and the screws P P, that pass through the conicalcap 0, the spring M can be adjusted.

Q is a slotted cylinder, having slots R R, corresponding to thewater-courses. S is the top piece of this cylinder. It is operated bythe eccentric T on the shaft U, which has a bearing, V, and ahand-wheel, W. The spaces of the cylinder between the slots are beveledin a direction opposite to that of the watercourses, as is shown in Fig.2.

The bottom of the flange D and the top of No. 218,301, dated August 5,1879; application filed May 9, 1879.

frame A are well ground in, so as to form close and tight joints.

X X are clamps which hold the flange D down onto the frame A.

The operation is as follows: The water is closed off by means of theflange-ring D, and the flow of Water is regulated by the cylinderring Q.If the machine is to be put in motion, the ring-flange D is turned bymeans of the rack and pinion so that the slots E are over the upperopenings of the water-course, and the water can enter into the same. Therapidity of the motion is regulated by opening more or less the loweropening of the watercourses by means of slotted cylinder Q and eccentricT. The spring M, which is regulated by the set-screws P P, is tocounteract the pressure of the water on the cap 0, and to prevent anundue amount of friction between the under side of D and the upper sideof A.

In case it may be necessary, several spiral springs may be arrangedbetween the bearingrings N and N.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. A gate for turbine water-wheels, consistingof a cap with slotted horizontal flange covering the upper openings anda slotted vertical cylinder covering the lower openings of thewater-courses, as and for the purpose set forth.

2. The combination of cap 0, provided with a flange, D, having slots E,of the frame A, having water-courses B B, of rack F, and of pinion G, asset forth.

3. The combination of the slotted cylinder Q, of water-courses B, and ofeccentric T, operating in the top plate, S, as and for the purpose setforth.

4. The combination of the cap 0, of one or more springs, M, wound aroundthe spindle K, of plate 0, and of set-screws P P, as and for the purposeset forth.
